Technical Field
The utility model belongs to the technical field of automobile part detection, and particularly relates to a rear axle air tightness detection tool.
Background
The rear axle is a rear driving shaft component for transmitting the power of the vehicle. It is composed of two half-bridges, and can implement half-bridge differential motion.
The rear axle is after production and processing accomplishes, need detect its gas tightness, and traditional detection mode is manual detection, and the operator is in the rear axle with gas injection promptly, and sealed back observation rear axle whether can appear leaking gas phenomenon, and this kind of mode need consume a large amount of manpowers, because the irregularity of rear axle structure, manual operation is difficult to realize the effective location to the rear axle, consequently is difficult to guarantee to detect the precision to manual operation detection efficiency is lower, should not use widely.
SUMMERY OF THE UTILITY MODEL
The utility model overcomes the defects of the prior art and provides a rear axle air tightness checking fixture to solve the problems in the prior art.
In order to achieve the purpose, the utility model adopts the technical scheme that: a rear axle air tightness detection tool comprises a case, an inflation head positioned on the case and positioning assemblies positioned at two ends of the case; the inflation head corresponds to the inflation hole position of the rear axle, the positioning assembly comprises a first supporting seat, a second supporting seat and a compression cylinder, a first positioning pin is arranged on the first supporting seat, a second positioning pin is arranged on the second supporting seat, and a pressing block is arranged at the end of a piston rod of the compression cylinder.
In a preferred embodiment of the present invention, a jacking cylinder is disposed in the chassis, and the inflation head is connected to a piston rod of the jacking cylinder.
In a preferred embodiment of the present invention, a marking machine is disposed on the chassis, and the marking machine corresponds to a position of the rear axle end.
In a preferred embodiment of the present invention, the number of the pressing cylinders is two.
In a preferred embodiment of the present invention, the compact is an L-shaped structure.
The utility model solves the defects in the background technology, and has the following beneficial effects:
under the matching action of the case, the inflation head and the positioning assembly, the utility model realizes the rapid detection of the air tightness of the rear axle, greatly reduces the labor intensity of workers, reduces the labor consumption, and can rapidly and effectively position the rear axle to ensure the detection precision.

The utility model is further explained below with reference to the figures and examples;
FIG. 1 is a schematic overall structure of a preferred embodiment of the present invention;
FIG. 2 is a partial schematic structural view of a preferred embodiment of the present invention;
in the figure: 1. a chassis; 2. an inflation head; 3. a positioning assembly; 31. a first support base; 32. a second support seat; 33. a pressing cylinder; 4. a first positioning pin; 5. a second positioning pin; 6. briquetting; 7. jacking a cylinder; 8. and (4) marking machine.
Detailed Description
The utility model will now be described in further detail with reference to the accompanying drawings and examples, which are simplified schematic drawings and illustrate only the basic structure of the utility model in a schematic manner, and thus show only the constituents relevant to the utility model.
As shown in fig. 1 and 2, a rear axle air tightness testing fixture comprises a case 1, an inflation head 2 located on the case 1, and positioning assemblies 3 located at two ends of the case 1; the inflation head 2 corresponds to the inflation hole of the rear axle, the positioning assembly 3 comprises a first supporting seat 31, a second supporting seat 32 and a pressing cylinder 33, a first positioning pin 4 is arranged on the first supporting seat 31, a second positioning pin 5 is arranged on the second supporting seat 32, and a pressing block 6 is arranged at the piston rod end of the pressing cylinder 33.
In this embodiment, place the rear axle on two sets of locating component 3, by first locating pin 4 on first supporting seat 31, second locating pin 5 on the second supporting seat 32 fixes a position the rear axle, compress tightly the rear axle by compressing tightly cylinder 33 drive briquetting 6 again, after the location is accomplished, inflation head 2 is the jacking under jacking cylinder 7 effect, get into the inflation hole of rear axle, inflate the rear axle, after inflating and accomplishing, take back inflation head 2 by jacking cylinder 7, observe the gas tightness condition of rear axle, if the testing result is the yields, then beat mark operation by marking machine 8 to this rear axle, record this rear axle as the yields, if the testing result is the yields, then beat mark operation can not carry out.
In this embodiment, a jacking cylinder 7 is arranged in the case 1, the inflation head 2 is connected with a piston rod of the jacking cylinder 7, the jacking cylinder 7 drives the inflation head 2 to move, and the rear axle is inflated.
Furthermore, a marking machine 8 is arranged on the case 1, the marking machine 8 corresponds to the end position of the rear axle, and the marking machine 8 marks the rear axle for marking.
Specifically, in the present embodiment, the number of the pressing cylinders 33 is two, which enables better pressing positioning of the rear axle.
In the present embodiment, the compact 6 is an L-shaped structure.
In summary, under the cooperation of the case 1, the inflation head 2 and the positioning assembly 3, the utility model realizes the rapid detection of the air tightness of the rear axle, greatly reduces the labor intensity of workers, reduces the manpower consumption, and can rapidly and effectively position the rear axle, thereby ensuring the detection precision.
In light of the foregoing description of the preferred embodiments of the present invention, it is to be understood that various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the utility model. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
